Fast Methods to Edit PDF Metadata

The metadata of PDF files holds high importance when dealing with PDF documents in a professional environment. PDF metadata represents the crux and most important details of PDF documents. If you deal with a large number of PDF files, you will need to deal with PDF metadata when trying to sort and save these files. You will often need to edit PDF metadata of different PDF files according to your personal or professional needs.

It requires you to have a tested and trusted tool when you need to change the PDF metadata of your PDF files. In this article, we guide you more about PDF metadata and the process of modifying it in PDF files.

Part 1: What is the PDF Metadata?

PDF metadata is the representation of the crux of PDF documents. It contains all the important information someone needs to learn about a PDF document without going through it. The metadata of PDFs is very important for companies and personnel dealing with a large number of PDF files. Without properly defined metadata in PDF files, finding a required file will become a hectic process. You can also say that metadata contains all the searchable details of a PDF file.

The metadata of PDF files contains details like title, author, subject, keywords, copyright information, document creation and modification date and time, etc. A few of the important fields when trying to change the metadata of PDF are summarized below:

1. Title

The file title doesn't mean the file name when dealing with PDF metadata. The file name and title don't need to be the same every time. In PDF metadata, the title consists of a brief but clearly described and accurate description of what your document is all about. When making a PDF document more accessible, defining proper title metadata is an essential requirement.

2. Author

The author's metadata deals with the basic question of who created the PDF. It is an important field where you can publish your name if you are the document creator. Otherwise, when reading the documents of different authors, you can sort and store your PDF documents by author name. It is especially helpful if you like to read a lot of eBooks.

3. Subject

The subject field in PDF metadata exists to complement the title field. If there is some information you have missed out in the title metadata, you can add it here. Otherwise, you can mention the important topics or subjects discussed in your PDF document. If you don’t want to add any new information, you can use the same information as the title metadata.

4. Keywords

It is among the essential metadata fields, as here you defined the keyword people can use to look for your PDF files. When adding keywords to the metadata of your documents, add the important words used in the document's title, subject, or headings. When adding different keywords, separate them by using semicolons instead of commas.
